Specification of Letters Patent.

Patented Jan. 15, 1918.

Application filed July 24, 1912. Serial No. 711,299.

To all whom it may concern:

Be it known that 1, WILLIAM HENRY FORD, citizen of the United States, resident of Niagara Falls, in the county of Niagara and State of New York, have made a certain new and useful Invention in Machines for Separating and Cleaning Grain; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 is a plan view of my invention as applied.

Fig. 2 is a side view of the same with the wheel at one side removed.

Fig. 3 is a side view of the invention as applied, the separator at one side being removed, and the parts of the invention being more fully shown.

The invention relates to mechanism for separating and cleaning grain, or for other purposes, wherein the material is operated upon by the reciprocation of a box or chest, into or through which it is fed, and the invention consists in the novel arrangement and combination of devices whereby the control of such chests is secured, as hereinafter set forth.

In order that they may withstand the violent reciprocations requisite for their functions, and because they are divided by many partitions into small cells, these chests are of necessity very strongly built, and hence have considerable weight. The rapid reciprocation of such a weight is a source of great danger to the building in which it is operated, as the rec ction of the moving forces of the chest must be taken up by the floor 11 on which it is placed, and through the cor communicated to the whole structure of the building, much to its detriment. The neutralization of these vibratory forces as regards their surroundings, and their self-absorption within the apparatus itself is de signed to be secured by the present invention.

In the accompanying drawings, the numeral 2, indicates a continuous base-frame, upon which are mounted one upon each end thereof, the separators 6. Each separator is directly supported by pedestals 4, at each of. its separate corners, these pedestals being secured rigidly to the base and serving as tracks for roller slides 5, fastened to the separator. Springs 15, extending below the track level, are provided to assist not only in checking the motion of each separator, at the end of the stroke, but also, by their reaction, the start of the return stroke. These springs are located substantially in the same horizontal plane as the crank shaft in order to avoid tilting or rocking of the separator and undue vibration.

Midway between the separators are placed bearings 7 supporting a shaft 8 substan tially at the level of the tracks, and pro vided with a central crank i) and two similar cranks 10, lying in the same plane as crank 9, but on the opposite side of the shaft. To the cranks 9 and 10 are connected the inner ends of oppositely extending pitmen 12 and 14, one of said pitmen being forked at 13 and both being located centrally of the separators, said pitmen having at their outer ends connection intermediatoly of the lengths of the separators, in the longitudinal vertical plane wherein lie the centers of gravity of the separators, and approaching the transverse vertical planes wherein lie such centers.

By the rotation of the crank shaft 8, the separators are given reciprocating motion which is at once equal and opposite. Having their centers of gravity in the same line, and being of substantially the same weight, and all reactionary stresses being resisted by the supporting base, the inertia of one separator is designed to be entirely counteracted by the inertia of the other, whether the separators are receding from or approaching each other.

Having thus described the invention, what I claim and desire to secure by Letters Patent is 1. The combination with two reciprocatory separators in line with each other and with their direction of motion, and a lon itudinal base frame and horizontal trac (s thereof supporting said separators, of boxes secured to said frame midway between the tracks of the separators, a transverse shaft having a central crank and side cranks opposite to and of equal length to that of said central crank and in the plane thereof, springs in the plane of the crank shaft connecting the separators to the base frame, and

pitman connections substantially in the plane of said tracks between the separators rators and having diametrically oppositecranks, oppositely extending pitmen at one end having connection with the cranks of said shaft and at their opposite ends havingconnection intern'iediately of the lengths of the separators in the plane of said shaft-and approachingthe transverse vertical planes wherein lie the centers ofv gravity of said separators, andspring connections between the separators and saidframe, also substan tially in the plane of saidshaft.

3. In combination, a longitudinal base frame. ha ring horizontal longitudinal tracks,

two reciprocatory separators sliding horizontally upon said tracks, a transverse shaft mounted upon said frame between said sepa rators and having diametrically opposite cranks located centrally of said separators oppositely extending pitmen also located centrally of the separators and having at one end connection with the cranks of said shaft and at theiropposite ends having oonnection intern'iediately of the lengths of the sepa'ators, in the plane of said shaft and substantially in the same longitudinal plane as the centers of gravity of the separators and approaching the transverse vertical planes wherein lie said centers, and spring connections between the separators and said frame, also substantially in the, plane of said shaft.

In testimony whereof I aliix my signature in presence of two Witnesses.
